CHAIN END INTERCONNECTING CLASP Filed July 18, 1967 snvntar United States 3,407,456 CHAIN END INTERCONNECTING CLASP William Frederick Addingtou, 2823 Terrace Drive, Chevy Chase, Md. 20015 Filed July 18, 1967, Ser. No. 654,282 2 Claims. (Cl. 24-232) ABSTRACT OF THE DISCLOSURE A clasp for interconnecting the ends of a chain including two parts sandwiched together and rotatable relative each other, one part having a hook and associated slots, the other part have aligned slots alignable with a radially extending slot defined by the hook.

SUMMARY OF THE INVENTION A chain end connecting clasp of generally circular configuration wherein a first part is formed from a blank of sheet material bent upon itself to form opposed aligned front and back portions and a second part of flat configuration is sandwiched between the front and back portions and rotatable relative thereto so that a chain end loop may be releasably retained between a hook formed on the second part and an associated perimeter of the first part.

BRIEF DESCRIPTION OF THE DRAWING DETAILED DESCRIPTION The clasp is composed of a first part 1 having front and back portions provided with aligned holes A, B for receiving pivot pin D and slots 4, 5 extending inwardly from the perimeters thereof and alignable with each other when the front and back are folded together to receive between them a second part 3 having a hook forming slots 6 which extend circumferentially about the perimeter and extend radially from the perimeter outwardly thereof.

The second part is provided with a stop shoulder adapted to engage end link 7 to limit relative rotation of the parts and a central opening C alignable with holes A, B for receiving pin D.

As shown in FIGURES 3 and 4 the chain end 8 is atent releasably secured to the clasp by first rotating the parts to the condition shown in FIGURE 3 and inserting link end 8 within slot 4, 5; part 3 is then rotated clock-wise to bring its hook under the link end and align radial slot 6 with slot 4, 5 whereupon the link end 8 may he slid down into the radial slot 6 defined by the hook; rotation of part 3 counter-clockwise from the solid line condition of FIG- URE 4 to the dotted line condition of FIGURE 4 catches the link end between the hook and the perimeter of part 1.

The other end link 7 is fixedly secured to the clasp so as to provide a stop for the unnumbered shoulder on part 3 to limit relative rotation of the sandwiched parts.

I claim:

1. A clasp for releasably holding securely together the free ends of a chain type necklace, said clasp comprising a first part having a front and a back joined to each other and spaced from each other a suitable distance, a second part sandwiched between said front and said back, and pivot pin means rotatably securing said parts together, said first part front and back each having opposed aligned slots dimensioned to receive an end link of a necklace free end, said second part having a hook, along a portion of the perimeter thereof which defines therewith a generally arcuate slot open at the free end thereof and a generally radially extending slot dimensioned so as to extend beyond the perimeter of the first part, said slot being arranged so that said necklace end link may be releasably secured to said clasp by first rotating the second part and associated hook so that the first part slots are unobstructed and inserting the end link therein, then rotating said second part so that the hook obstructs said first part slots and the radial slot is aligned with the first part slots and moving the end link into said radial slot, and then rotating said second part, associated hook, and associated end link so that the end link is caught between the hook and the perimeter of the first part.

2. A clasp as recited in claim 1 wherein the other end link is secured to the first part so as to extend from front to back and present an abutment engageable with a stop formed on the second part to limit the relative rotation of the sandwiched parts.
